2017 marks the 40th anniversary of conrad-johnson design inc. and to celebrate, we are introducing two new anniversary tube amplifiers – the ART150 and ART300. These amplifiers employ the recently developed KT150 output tubes. A single pair of KT150s produces 150 Watts per channel in the ART150 stereo amplifier, while two pair produce 300 Watts in the ART300 mono-block.

In addition to utilizing the KT150 output tubes, the ART150 and ART300 feature new input and inverter stages using 6922s for voltage gain, main power supply reservoirs boasting a more than ten-fold increase in total capacitance compared to our earlier ART mono-blocks and ARTSA amplifiers, and a new regulator circuit for the input stage power supply.

The ART150 and ART300 boast dramatic new styling, yet clearly show their conrad-johnson heritage. The output tubes are showcased behind a clear window spanning the full width of the protective tube cage, while the input tubes are enshrouded in a clear protective block.

ART150s are expected to be available for delivery by mid-May, with ART300s to follow a few weeks after. As with earlier anniversary products, production will be limited to 250 units of the ART150 and 125 pairs of the ART300. Projected US suggested retail prices are $18,500 for the ART150 and $18,000 each for the ART300s.

These new models will replace the now discontinued ARTSA and ART mono-blocks.
